BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a bucket, and more particularly to an innovative bucket composed of an external cylinder and internal container, the internal container and external cylinder being positioned by the top.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98

The currently available bucket products still have some shortcomings, for example, as shown in FIGS. 1 and 2, the bucket 11 of typical toilet brush set 10 is composed of an annular metal cylinder 111 and a metal bottom plate 112 sealed at the bottom of the annular metal cylinder 111. A cup 12 is embedded into the bucket 11 to accommodate the sewage dripped from the toilet brush 13; however, there are shortcomings for the typical bucket observed during actual applications.

First, due to the structural requirement that a metal bottom plate 112 must be sealed at the bottom of the annular metal cylinder 111 of the bucket 11, costs will rise substantially with the growing price of metal materials. If the metal bottom plate 112 is sealed onto the annular metal cylinder 111, a special process (punching and rolling) must be performed, leading to higher manufacturing cost and lower manufacturing efficiency.

Second, if the inner space formed by the annular metal cylinder 111 and metal bottom plate 112 of the bucket 11 is used to accommodate the sewage dripped from the toilet brush 13, corrosion or damage may occur quickly; hence, a cup 12 is embedded into the bucket 11. In such a case, the cost of components will increase accordingly. Moreover, since there is still a gap between the cup 12 and annular metal cylinder 111, when water flow occurs from the external wall of the cup 12 or annular metal cylinder 111, corrosion still exists at the joint between the metal bottom plate 112 and annular metal cylinder 111.

Third, from the perspective of the users, as the cup 12 embedded into the typical bucket 11 is used to accommodate the sewage dripped from the toilet brush 13, the sewage has to be removed by manually taking out the cup 12 from the bucket 11, leading to inconvenience of operation due to limited space of the bucket 11.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.

Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.

BRIEF SUMMARY OF THE INVENTION

Based on the unique bucket of the present invention, a top periphery of the internal container and top opening of the external cylinder are assembled securely, and the bottom of the external cylinder is provided with an opening. The metal bottom plate of prior art can be neglected, and material cost and processing procedure can be reduced, thus cutting down the cost of materials and processing with better industrial efficiency.

As the external cylinder and internal container are made of metals and plastics, the sewage from the toilet brush can directly drip into the plastic internal container, thus preventing corrosion and extending the service life.

Based on the characteristic of the top periphery of the internal container and top opening of the external cylinder being assembled securely, the sewage from the bucket can be discharged directly without need of manual operation, thus realizing ease-of-operation with improved applicability.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 3-4 depict preferred embodiments of a bucket and toilet brush of the present invention. The embodiments are provided for only explanatory objectives with respect to the patent claims.

The toilet brush set A comprises a bucket 20, which contains an external cylinder 21 and an internal container 22. The external cylinder 21, made of metals, contains a cylinder body 211, a top opening 212 and a bottom opening 213. The internal container 22, made of plastics, contains an accommodation space 221 and a top periphery 222. The top periphery 222 of the internal container 22 is mated with the top opening 212 of the external cylinder 21.

A toilet brush 30 contains a handle 31 and a brushing portion 32 at one end of the handle 31. The brushing portion 32 can be placed into the accommodation space 221 of the internal container 22 of the bucket 20. The top of the handle 31 is protruded from the top of the bucket 20.

A lid 40 is set at a preset location of the handle 31 of the toilet brush 30. The lid 40 can be used to cover the top opening 212 of the external cylinder 21 of the bucket 20, thus realizing the secure positioning of the toilet brush 30 and bucket 20.

Next, the assembly and positioning of the top periphery 222 of the internal container 22 and the top opening 212 of the external cylinder 21 are described.

Referring to FIG. 6, the top opening 212 of the external cylinder 21 is clamped securely onto the top periphery 222 of the internal container 22 via an inward curved portion 23. The top periphery 222 of the internal container 22 can be formed into a curved or curled portion for embedding into the inward curved portion 23 formed by the top opening 212 of the external cylinder 21. The top periphery 222 of the internal container 22 can be embedded into the inward curved portion 23 in multiple patterns. Referring to FIG. 7, the top periphery 222 of the internal container 22 can be preset into an outward folding pattern. So, the top periphery 222 can be extruded into a S-shaped curved portion 223 when the inward curved portion 23 for the top opening 212 of the external cylinder 21 is punched (or rolled). Referring also to FIG. 8, the top periphery 222 of the internal container 22 can also be preset into an inward folding pattern. So, top periphery 222 can be extruded into an S-shaped inward curved portion 224 when the inward curved portion 23 for the top opening 212 of the external cylinder 21 is punched or rolled. Referring also to FIG. 9, the top periphery 222 of the internal container 22 can also be preset into a straight pattern. So, the top periphery 222 of the internal container 22 can be extruded into a curved portion 225 when the inward curved portion 23 for the top opening 212 of the external cylinder 21 is punched or rolled.

Furthermore, the bucket 20B formed by the external cylinder 21 and internal container 22 is shown in FIG. 10, wherein it can be used as a garbage bin due to expanded space.
